FOOD CUTTING APPARATUS
A food cutting apparatus has an upper plate housing connected to a lower plate housing and capable of being moved from an open position to a closed position where the upper plate housing is adjacent to the lower plate housing. The lower plate housing includes a base capable of being supported on a flat surface. A floating upper plate is disposed in the upper plate housing and the upper plate is capable of moving within the upper plate housing. A floating lower plate is similarly disposed in the lower plate housing and the lower plate is capable of moving within the lower plate housing.
This application claims the benefit of U.S. Provisional Patent Application No. 62/085,139, filed Nov. 26, 2014. The disclosure of this prior application is incorporated herein by reference in its entirety.
BACKGROUNDThis invention relates to an apparatus used to hold food items for slicing or cutting, and in particular for cutting the food items into pieces of generally equal size. Cutting small foods such as cherry tomatoes or grapes in such a manner can be difficult. One method that is currently used is to place the small food item on a first plate, and then place a second plate on top of the small food item to hold the small food item in the gap between both plates. The user holds the top plate with one hand and uses the other hand to slice the small food item with a knife. It can be difficult to hold the plates in place, and this method can be dangerous. Other known holders do not accommodate foods of different sizes and thicknesses.
SUMMARYThe food cutting apparatus disclosed herein is intended for use with a kitchen knife or other slicer for slicing food items ranging in size and shape from small, generally spherical items such as grapes or cherry tomatoes, to bulkier and thicker items such as bagels or filets. The apparatus includes two opposing floating plates contained within an upper plate housing and a lower plate housing. The opposing plates are both spring-loaded to permit them to move with respect to one another. The upper plate housing and lower plate housing are connected by a hinge such that the apparatus is capable of holding food centrally to a gap between the two opposing plates. As will be described in greater detail below, when a food item is placed on the lower spring-loaded plate and the upper spring-loaded plate is closed over the food item, the gap formed between the two plates enables a user to use a slicer, such as a knife having an appropriate length, to safely slice the food item, while retaining the food item in the proper location for cutting at a central position. This enables the user to easily and consistently cut the food items into pieces of approximately equal sizes.
A better understanding of the invention will be obtained from the following detailed descriptions and accompanying drawings, which set forth illustrative embodiments that are indicative of the various ways in which the principals of the invention may be employed.
The description that follows describes, illustrates and exemplifies one or more embodiments of the invention in accordance with its principles.

As can be seen in
The lower plate housing 104 forms the base of the food cutting apparatus 100. In one embodiment, as depicted in
As depicted in
A notch 115 extends inwardly formed in top perimeter surface 114, and recess 117 is formed in lower plate 110 to fit notch 115. This arrangement prevents lower plate 110 from rotating, and the gap between notch 115 and recess 117 can permit fluid created during the cutting process to drain into lower section 142. A similar notch 116 is formed in bottom perimeter surface 107, and recess 118 is formed in upper plate 106 to fit notch 116 to prevent upper plate 106 from rotating. It should be noted that it is preferred that upper plate 106 be rotated 180 degrees from the position shown in, e.g.,
A first plurality of recesses 126 is formed along the perimeter of the upper plate 106 and, as shown most clearly in
As depicted in
A plurality of feet 124 may be attached under the bottom of lower plate housing 104. The feet 124 help to prevent scratching a surface with the bottom edge 119 of the bottom sidewall section 112, and they may be constructed of a material that prevents slipping and movement of the food cutting apparatus 100.
Turning to
Similarly, a second plurality of springs 204 connect lower plate 110 to the interior of lower plate housing 104 so that lower plate 110 is movable within lower plate housing 104. A plurality of spring housings 208 are formed on the inner surface 214 of lower plate housing 104, and a correspondingly aligned plurality of retention pegs 216 extend from the bottom surface 223 of lower plate 110; each of the springs 204 are retained by one of the spring housings 208 and one of the retention pegs 216. As with the top portion, the range of motion of lower plate 110 is limited by the bottom surface 209 of each spring housing 208, which contacts the bottom surface 223 of lower plate 110 before springs 204 are fully compressed. Retention pegs 216 may be longer than retention pegs 212, since pegs 216 can extend through opening 141. Springs 202, 204 are generally in the non-compressed position prior to use of the apparatus 100.
It is preferred that apparatus 100 uses three springs 202 in the upper plate housing 102 and three springs 204 in the lower plate housing 104, and that these two sets of preferably identical springs be located in the same locations in both housings, directly opposite one another, so that the upper plate 106 and lower plate 110 are balanced with respect to one another and the compression of the two plates 106, 110 is equal and consistent. The preferred location of springs 202 is shown in dotted lines in
Turning to
The knife blade (not shown) is then placed on the front edge of top perimeter surface 114, opposite hinge 130 and preferably adjacent to the closest food item 300 (i.e., to the right in
As noted, apparatus 100 may be used with a plurality of smaller items, and the lower plate 110 may be filled with these food items. It is preferred that such smaller food items be roughly all the same size, as the larger items will control the displacement of the plates 106, 110 and smaller items will be cut at an offset. Alternatively, a single larger food item such as a bagel or filet can be placed on lower plate 110, provided that the food item does not extend past the sides of lower plate 110.
The amount of pressure required to be applied in order to close the upper plate housing 102 on the knife blade depends on the size of the food item(s); it is important that the user retain a steady pressure throughout the cutting process so that each food item stays in the same relative location with respect to the other food items, to enable a consistent cut. Given that springs 202 and 204 are preferably identical, the amount of this depression should be equal on both plates 106, 110.
Apparatus 100 is intended for use with a standard kitchen knife, and it should be appreciated that the knife should be long enough so that its tip can be seen when the unit is closed (i.e., it should extend past finger guard 108), so that the back and forth sawing motion does not inadvertently pull the tip entirely into the housing, where it can get caught inside and damage the unit, or at least require the user to start over and risk ruining the cut food items. A knife that is beveled on both sides is preferable, as that style of knife will tend to cut evenly, whereas a knife that has a single beveled edge will tend to cut at a slight angle, thus cutting some of the food items in half, but cutting other food items closer to the back of the unit at an offset.
It should be appreciated that upper plate 106 and lower plate 110 are parallel to one another in the closed position, and are preferably disposed at an angle from the horizontal of approximately six (6) degrees, to make the cutting process easier. Specifically, it has been found that when a plurality of small spherical food items 300 are placed on the lower plate 110, this angle with respect to bottom edge 119 causes the food items 300 to collect near the side of lower plate 110 closest to hinge 130. It is preferred to have these food items 300 collected together so that they remain in place when the knife blade first contacts them, especially when lower plate 110 is only partially filled.
As depicted in
While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the appended claims and any equivalent thereof.
